Thank you for drawing my attention to the "The Basics" section. Your 2 and 3 are obviously incorrect: Indeed, the fact me and others like Kenny are encountering this problem attests to the fact 2 is incorrect. Also (though I think you already know this) portals are only spawned in the opposite dimension on using a portal, not when lighting them. You should probably update the original post to reflect this.
Also:

I think you meant to say Nether portals here, that makes more sense. And it's true. I'm guessing the search range is currently 128 (closest power of 2 to the testing results), and 128 * 8 = 1024 which is why you have to walk an absurdly large distance to have the game auto-spawn a portal correctly (Going Earth to Nether).
The portal search in the nether needs to be 1/8 the search range on the overworld to account for the compression ratio (eg only searches nearest 16 blocks in the Nether, the way it was originally before the first patch). I have put this up on the bug tracker site, but it sadly seems to be being ignored... =(
I'll remove the word activate from my 2 and 3. It was intended to imply stepping into the portal, but "use" is good enough by itself.
And i agree that the surface-to-Nether search needs to be 1/8th of the nether-to-surface search to help resolve the minimal distance issue.
Which is, again, not the case. Listen to what the guy said:
Quote from Kenny1264 »
I traveled at least over 100 blocks over water and made a water base, which i just put portal C in, but it links all the way back to B when there should be room for it to be closer to where portal D should be.
Over 100 blocks Overworld (Let's go 400 for simplicity, 50 blocks Nether) is still plenty of space for the game to generate a portal. The bug currently is that, until a certain distance is passed, the game favors linking to an existing portal over generating a new one. That's why his portal D is going all the way back to B, and that's why we need to manual build. The terrain is a factor, yes, but not the be all end all thing you're describing it as.
Yup, that is the bug.
The terrain is not the only factor.
If the portals are too close they will link to nearby portals.
you should go back and read "the basics" in my original post.
In my original post i have written:
8. The minimal distance between perfectly aligned portals** is 16 blocks on the surface, 1 block in the Nether, which is 16(1)
**If portals are not perfectly aligned i recommend at least 80(10) 80 blocks on the surface, 10 blocks in the Nether as recommended in my example. For the best results I suggest at least 128(16) because there seems to be a 1 portal per Nether chunk (16x16 area) limit, further testing required.
And then i wrote
it is probably just bugging out because it is too close in the Nether to auto-spawn a portal
His 2 surface portals are within 100 blocks of each other and his new nether portal will have to be built manually.
I can tell you right now there is an obstruction in the way.
Actually, there probably isn't. I've run the tests many times on my own game. The search portals do for an existing portal is far to large for the Nether, so it frequently links up to a different portal instead of attempting to make another one.
And my next 2 sentences were...
Clear the obstruction, build portal C.
If there is no obstruction it is probably just bugging out because it is too close in the Nether to auto-spawn a portal, just build Portal C 12-13 blocks away from portal A and it will link up with portal D on the surface.
You can use that effect to essentially glitch mine obsidian. travel through A, back through C, destroy D and take obsidian, go back through A, through C, game will remake D. All portals are still there, and you've gained 10 obsidian.
If you are doing this you might as well just do the portal duplication glitch.
Place a chest outside of your portal.
Place items in the chest.
Enter the portal and once the screen starts to wave open the chest.
Once teleported through your chest will still be open and you can remove items without removing them from the original chest.
By placing chests next to your surface portal and Nether portal you will double your items every time you use the portals and quickly fill the chests with stacks of whatever.
Start with 1 obsidian and within 5 minutes you will have 2 double chests packed with full stacks.
This is very helpful, but I've run into a different problem with portals.
I've made a portal A on earth and it links to B in the Nether and it links back to A just fine.
But I traveled at least over 100 blocks over water and made a water base, which i just put portal C in, but it links all the way back to B when there should be room for it to be closer to where portal D should be.
Also, portal B still links to A.
I hope that's understandable. This is really bugging me, as it takes around 2 minutes by boat to get from my house to my sea base.
It is the same exact problem, but with a functional A and B and an obstruction preventing C.
This is your situation.
Everytime you create a new portal (portal D) it just links back to your Portal B.
Here is how to fix.
Find out where your game wants to make Portal C, in this picture it is marked with an X.
You have no choice but to build Portal C yourself in the Nether.
1. Count the distance between Portal D and Portal A, in this case you said it was 100 blocks away.
2. Divide by 8, 100/8 = 12.5 blocks.
3. Face the direction of Portal D
4. Enter Portal A, walk 12.5 blocks and build Portal C.
I can tell you right now there is an obstruction in the way.
Clear the obstruction, build Portal C.
If there is no obstruction it is probably just bugging out because it is too close in the Nether to auto-spawn a portal, just build Portal C 12-13 blocks away from portal A and it will link up with portal D on the surface.
Incidentally, Notch has added coordinates to the F3 debug screen, so it's even easier to get these portals aligned (you don't need to download an extra program). Just remember: the X and Z coordinates in the Nether should be 1/8th of the values in the overworld. (The Y coordinate doesn't matter, but technically it should be the same in both.)
I'll have to look into this once i'm done with New Vegas.
Yes, minecarts in MineCraft are implemented very poorly.
Yes, some people like to use work-arounds like cart boosters to get decent use out of them.
Yes, some people like to use words like "fag" and "GTFO" to show how great they are (ironically, proving the opposite in doing so).
Yes, AutoCart has shown how a simple but effective cart system should be.
Yes, Notch will get around to implementing a good minecart system one day (that may be a long time away)
Yes, you could try using twitter to let Notch know that you're not happy with minecarts (although, unless you're Swedish or from a game magazine, your replies might be rare. lol)
Yes, you could try using the new bug tracker/feature request to give Notch a nudge, and hope that it differs from Twitter in deciding which ones are read. :wink.gif:
Yes, I've used the word Yes way too many times, and should refrain from using it again for at least a week to make up for it.
1. The Nether correlates to the surface world with an 8:1 ratio. (1 chunk = a 2x2 area.)
2. Building a portal on the surface will spawn a portal in the Nether (after you use the portal)
3. Building a portal in the Nether will spawn a portal on the surface (after you use the portal)
4. 8 blocks on the surface = 1 block in the Nether. = 8(1)
5. The surface and the Nether share the same cardinal directions.
6. You maintain your direction when you enter the Nether.
7. The correlation spots only change as you move horizontally through either world. you can freely change the elevation of your portals in either world and it will maintain its correlation spot in the other world.
8. The minimal distance between [b]perfectly aligned portals**[/b] is 16 blocks on the surface, 1 block in the Nether, which is 16(1)
[b]**[/b]If portals are not perfectly aligned i recommend [b]at least 80(10)[/b] 80 blocks on the surface, 10 blocks in the Nether as recommended in my example. For the best results I suggest [b]at least 128(16) because there seems to be a 1 portal per Nether chunk (16x16 area) limit, further testing required.
[b]The Problem[/b]
You build a portal on the surface and name it Portal A.
You enter portal A and get a loading screen: “Entering the Nether”
The game looks "down" at the correlated spot in the Nether but it is unsafe for a portal,
[b]The problem is because it does NOT build Portal B![/b]
In this example it cannot build it because a mountain is in the way.
The game finds the nearest safe place to create a portal, which is 10 blocks north, and it is named Portal C.
The Nether loads and you are standing inside of portal C.
You don’t realize the problem yet, to you it appears that everything went smoothly.
You step back into Portal C, you get a loading screening: “Now leaving the Nether”
The game looks "up" at the correlated spot for Portal C which is exactly 80 blocks north of your original portal, it is safe and the closest spot, so it creates a new portal. Portal D.
You load back on the surface in portal D, 80 blocks north of Portal A.
Portal C and D are connected as entrance/exit, but Portal A only acts as an entrance to Portal C.
[b]How to Fix.[/b]
You need to build Portal B!
The first thing you need to do is find out where Portal B needs to be built in the Nether by measuring the distance between Portal D and portal A.
In this example they are 80 blocks apart.
[b]Divide by 8.[/b]
[b]For long distances, 100+ blocks, simply count how long it takes to cross that distance and divide by 8[/b], this is approximately how long it will take to walk to Portal B's spot in the Nether.
Enter Portal D facing in the direction of Portal A.
When you load in the Nether you will be facing the direction in which the obstruction exists.
Remove the obstruction.
[b]- If it is a wall/mountain you will need to dig out a space for a portal.
- if it is a lava lake you will have to build a platform
- If it is lava fall you will have to divert the falls.[/b]
with the obstruction cleared count 10 blocks and build portal B
When you enter portal B the game will look at the surface and find Portal A.
Portal B and portal A will now function as 2 way portals connected to each other.
You can now destroy both Portal C and Portal D if you don’t want them.
Portals getting spawned on death is a real bug(?). I've managed to get them quite a few times, they really stick out with a Cartograph of your map.
It's basically the result of the game making you exit the Nether on death the same way it normally swaps dimensions: with the Portals. Your point of death is treated as the entry Portal, and an Exit Portal is generated at the corresponding spot in the Overworld before you are moved back to spawn.
You can test this by entering the Nether, picking a random direction and moving that way for a significant distance. Then get killed by whatever means (Ghast, lava, Zombie Pigman, burning.... so much choice!). Now you should see a random chunk, with a portal directly at the centre (unless it spawned underground), when you render your map with Cartograph.
Also I am wondering why sometimes people just find portals that they never created. As in say a player creates portal D and C, and they link to eachother, and they find portal A, a portal they never created.
There has been some speculation, that a portal is created on player death in the Nether, at the point where the player died. Notch may have implemented that, to try and ensure that people have at least some chance of getting their equipment back.
This is pure speculation, but it is also possible that the system occasionally tries to create duplicate portals, which have a closer overworld correspondence with the Nether location that is being asked for, as well; but that for some reason, the player is still only sent through the portal they themselves created. Such a duplication effect would most likely occur when the player goes to leave the Nether.
Portals spawned on death? I'll have to test this now...
I don't know yet.
These are a good questions and i've experienced those problems before.
Personally i consider extra portals to be the real portal bug because they seem, so far, to be illogical actions performed by the portals.
One of my first portals would spawn an extra portal somewhere within ~200 blocks every time i used it but still acted as a 2 way portal... I adjusted the location of the Nether portal slightly and the extra portals stopped spawning.
Those extra portals appeared even though i never entered or exited them plus They appeared at distances and in directions that didn't make any sense.
At first i thought these were the so called "natural portals" but they stop spawning once all your portals are properly linked so they are somehow connected to the same issue of safe spots and Nether obstructions.
I built one near my spawn, just to get hell materials and for faster travel later on. Some time afterwards, I began a search for a snowy biome to put a nice mountain base in. After some sailing, I found a gorgeous piece of mountainous snowy wonderland. It was rather far from my base, though, so I decided to build a portal in the snow and make a path to the portal by my spawn. I dug out a room and built the portal, went into it, and found myself in the portal base I built on the nether side of my spawn portal. Confused, I went back through the portal and found myself on earth in the portal by my spawn.
I tried going back to the snowy portal and back in, putting out and re-lighting the portal, exploring towards where snowy portal should be in the Nether, everything. But whenever I used the snowy portal, I found myself back in the Nether base by my spawn.
Does anyone know how or why this is happening? I would really appreciate an explanation or advice on what I should do.
I'm fairly sure that the "desired" Y coordinate between the two dimensions are mapped 1:1. But the game will vary this as well when it tries to locate a safe spot to place the created portal. Even so, a portal near bedrock on one side will tend to create a portal near bedrock on the other side (provided that there's a landing spot). Portals near the surface will probably be better matched at first, though, since there's more open space and less chance of a obstruction at the desired coordinates.
Best guess, but I haven't done any testing on this, is that it first searches for any existing portals in the same chunk as where it's supposed to land, and failing that searches outwards in a sphere from the desired coordinates and creates a new portal in the closest direct-line location that's large enough and has a safe floor. (Although since some people have reported flying portals, it's likely that it only needs one or two blocks of floor, and it replaces them as part of creation.)
I think this is true, i've noticed that mountain top portals will appear higher and bedrock portals will appear lower in the Nether.
What I'm not sure about is whether or not the game will search the entire Nether vertically before moving to a "closer" horizontal safe location.
If there is a safe spot 50 blocks vertically (which would maintain a functional 2 way portal) and another safe spot 10 blocks horizontally (which will begin the portal problem) will it choose to move horizontally?
Hopefully the portals exhaust all possible vertical locations before moving horizontally but this would be tough to confirm.
